My Raised Vent goes up then right back down without doing anything else. I have cleaned the control pad. I can not find the mother board or limit switches. Are they inside doen below? I have tried to remove the entire unit but the cooktop is slightly ontop of the vent lip and I am afraid of breaking it. What is my problem?
Thanks. I am not comfortable in removing the cooktop. I have a remote external blower. I have to remove some nice carpentry to access the sides so is the main board on the left if I am looking at the back? Will I be able to access the limit switches any other way. I don’t even know if they are my problem. Thanks
I’m not able to give you more specific advise because of incomplete or wrong model number.

Gene, I have a PVR36S with the exact problem. Goes up then down and recycles - can only stop by unplugging. I have replaced both the up and down limit switches and it still does the same thing. Any other ideas?
